Chuck Lever 760e1a2e4d xprtrdma: Fix completion wait during device removal 
commit 13cb886c591f341a8759f175292ddf978ef903a1 upstream.

I've found that on occasion, "rmmod <dev>" will hang while if an NFS
is under load.

Ensure that ri_remove_done is initialized only just before the
transport is woken up to force a close. This avoids the completion
possibly getting initialized again while the CM event handler is
waiting for a wake-up.

Fixes: bebd031866 ("xprtrdma: Support unplugging an HCA from under an NFS mount")
